State road B 6 near Eichenbrunn: Refurbishment brings new security!

State road B 6 near Eichenbrunn: Refurbishment brings new security!

In an important step to improve the infrastructure, the state road B 6 between Eichenbrunn and Klement was extensively renewed. This measure became necessary because the section affected had numerous road damage, including settings, tracks, outbursts and a lack of grip. The damage made it necessary to renew the road surface to ensure traffic safety. The state road section has a length of around 800 meters and comprises an area of around 5,200 square meters, through which around 4,000 vehicles roll every day. Therefore, a quick and effective implementation of the project was important in order not to disturb the flow of traffic.

The renewal is carried out by the cement stabilization of the soil. Initially, the delayed lane edges with an unbound support layer was reinforced. After that, the damaged asphalt layers were milled and prepared according to plan. Then a layer of about 15 cm additional material was used, which was milled through with an unbound layer of support and cement and then compressed to a 25 cm thick cement stabilized layer. Finally, an 8 cm thick bituminous base layer and a 3 cm thick bituminous cover layer were applied on this stabilized layer, which forms the new road surface.

The framework of the conversion measure

These comprehensive work was carried out by the Held+Francke company under a roadblock and should be completed within three weeks. After completing the work, the Laa road maintenance department will also take over the restoration of road equipment and the adjustment of the banquets. The total cost of this extensive road renewal is around 340,000 euros and are fully borne by the state of Lower Austria.

A central aspect in such construction projects is the recycling of soil excavation, which takes place as part of the renewal in accordance with the circular economy law (KRWG). The recycling of the soil excavation helps to reduce the dismantling of primary raw materials, which not only entails economic but also ecological advantages. In modern construction processes, mineral materials are replaced by naturally upcoming soils, which contributes to efficient use of resources.

circular economy in construction

The construction industry has been very interested in the efficient use of raw and building materials for many years, as this offers both economic advantages and benefits the environment. Due to the considerable annual needs in the construction industry, including around 207 million tons of mineral construction waste in Germany, the recycling of building materials plays an important role. Around 90 % of these waste is now used in an environmentally friendly manner, which helps the construction industry to sustainably reduce the resource requirements in construction.

Developments in the area of soil strength and compliance with the replacement building materials regulation are crucial to ensure the resistance of the soil. Innovative treatment methods can increase the pressure resistance and frost resistance of the soil, which is particularly important for fine -grained and binding soils. A careful relationship between the cement content and construction process is required to achieve the desired quality of the load capacity.
